Its not the 420 code. Its a catylic converter specific code (forgot exactly which, ill know by tomorrow). As for the 80,000... no dice, im closing in on 87,000 miles. I already did the uim/lim cleaning, all o2 sensors have been replaced, new plugs, new wires. Does anybody think that good gas will help any? I run whatever is the cheapest in the area (usually citgo 87 octane).
